‘James Comey is a proven LEAKER & LIAR. Virtually everyone in Washington thought he should be fired for the terrible job he did – until he was, in fact, fired.’ – President Donald Trump

When President Trump sacked James Comey as FBI Director in May last year, he ignited a political firestorm with huge implications for American democracy. Comey’s dismissal led to the appointment of Special Counsel Robert Mueller to look at possible links between the Russian government and the Trump campaign — an investigation which may bring to light dark secrets about President Trump and his close associates. Now to mark the publication of his global bestseller, A Higher Loyalty, Comey comes to the Intelligence Squared stage for an exclusive event. In conversation with the BBC’s Emily Maitlis, he will reveal what really happened in those strange early months of the Trump presidency, as well as his long career in public service and speaking truth to power.

Before his tenure at the head of the FBI under Obama from 2013 to 2017, Comey served in the highest echelons of American law enforcement, first as a senior prosecutor during the Clinton administration and then as Deputy Attorney General under President George W. Bush. His career under both Republican and Democratic presidents brought him to the centre of the most important cases in modern history, including prosecuting the mafia, overhauling the Bush administration’s surveillance and counterterrorism policies, securing the conviction of lifestyle guru Martha Stewart and leading the controversial investigation into Hillary Clinton’s private email server.

In today’s era of fake news, polarised politics and ‘alternative facts’ — when the truth itself often seems under attack — integrity, honesty and ethical leadership seem more important than ever. Comey, who served under four very different presidents, has witnessed and experienced the struggles that arise when patriotism and principles careen headlong into the partisanship that has gripped American politics.
